At times i would have to drive in a valley a small distance from the Pacific Ocean, Interstate 5, the fog could get heavy.
I noticed most of the foreign sports cars could see well enough to pass all of the US vehicles in that fog.
I looked through some catalogs & a company named Trail-Gear used to carry short light bars & short orange lenses (3) for the short light bar
It made enough of a difference, that i became the lead vehicle of the U.S. vehicles.
I also turned my cargo light ON, because i noticed i could judge my distance from other pickups in the fog, when they had the cargo lights on
